Smart card device and method used for transmitting and receiving secure e-mails
First Claim
1. A smart card system for transmitting and receiving secure e-mails comprising:
- a smart card device reader adapted to be connected to a host having a client e-mail program for transmitting and/or receiving e-mails to and/or from an e-mail server;
a smart card device received within the smart card device reader and comprising,a card body; and
an integrated circuit carried by the card body and comprisinga memory for storing a set of instructions relating to initiating and completing smart card transactions between the smart card device and a port of the host and for storing both private and public keys for an encryption algorithm, anda processor operative for communicating with the host via the smart card reader and operative for transferring e-mails to and/or from the client e-mail program and the e-mail server via the smart card device while decrypting and encrypting any transmitted and/or received e-mails within the smart card device, wherein said memory is operative for storing a smart card device IP address for an email server, and a Simple Mail Transfer Protocol (SMTP) outgoing parameter is set to the smart card device IP address such that the smart card device is operative as a gateway from a client email program.

Abstract
A system and method for transmitting and receiving secure e-mails is disclosed. A smart card device stores both private and public keys for an encryption algorithm. The smart card device is preferably a USB smart card device and interfaces a host having a client e-mail program. E-mails are transferred to and/or from the client e-mail program and e-mail server via the smart card while decrypting and encrypting any transmitted and/or received e-mails within the smart card device. The smart card device stores an IP address for an e-mail server. A Simple Mail Transfer Protocol outgoing parameter is set from the client e-mail program to an IP address for the smart card device.
